It's not really a problem, but consider:
Alice is a stockbroker, Bob is a day-trader,
Bob needs a stock bought or sold at a certain time, which changes quickly in
value throughout the day.
With the notary as a simultaneous cc recipient and sender, it can add a time
verification to the transaction.
just a suggestion for a practical application at the user end.
